In neutrino oscillation the probability a neutrino changing its flavour depends on the difference between the squares of the masses of the neutrino mass eigenstates. For example, the squared-mass difference between the mass states [itex]\nu_{1}[/itex] and [itex]\nu_{2}[/itex] is denoted [itex] \Delta m^2_{12} [/itex].(adsbygoogle = window.adsbygoogle || []).push({});

However, I keep reading stuff that refers to the neutrino source used in the experiment when it talks about the mass difference, for example, in solar neutrinos it is [itex] \Delta m^2_{sol} [/itex].

Am I right in thinking that whenever I see [itex] \Delta m^2_{sol} [/itex] it will always mean [itex] \Delta m^2_{12} [/itex] etc.?
